"Hi stranger! I'm Jack, Joystick's old friend. If you find this letter, you may be the chosen one. I present myself. My name is Jack Korn. I'm a retired pirate. Young, I traveled through the world in search of treasures.
During my life I fought with a lot of captains and their crew... And one day, I fought with Sir Marshmellow. I won and took possession of his crew and his ship. A piece of paper was hidden in a book. His newspaper. It was a treasure map.
My crew and I traveled through the Qbee world to find this treasure. 2 years navigating to finally find this island. There was a Temple. We got through these ruins and found a secret room. There was an enigm on the door in front of us. This enigm was : 'I have 2 feet, 6 legs, 8 arms, 2 heads and an eye. Who am I ?'.
My crew gave up quickly. But I stayed. I stayed 2 weeks thinking about this and eating snails and caterpillars. I finally found the answer and the door opened.
I kept a big part of the treasure with me. But I left some for the one who will find the same answer I found.
Once you get it, find an Imperium that remains black. The south is the opposite.
Good Luck! - Jack "
(This is not a joke, some items are really hidden somewhere and are waiting for you)
